The Dark Photon in the PHELEX Experiment
A. V. Kopylov, I. V. Orekhov, V. V. Petukhov +1
This paper presents diurnal measurements of the single-electron count rate in the PHELEX experiment using multi-cathode counters over the period from 2023 to 2026. The results obta…
Do We Observe Dark Photons in PHELEX with a Multi-Cathode Counter?
Anatoly Kopylov, Igor Orekhov, Valery Petukhov
In this paper, we report the results obtained in the PHoton ELectron EXperiment (PHELEX) during 208 days of measurements in the search for dark photons using a multi-cathode counte…
The Latest Results of Experiment on The Search for Dark Photons With a Multicathode Counter
A. V. Kopylov, I. V. Orekhov, V. V. Petukhov
The technique is described of the search for dark photons with a multicathode counter. The aim of experiment is to search for diurnal variations of the effect from conversion of da…
Diurnal variations of the count rates from dark photons in PHELEX
A. Kopylov, I. Orekhov, V. Petukhov
We describe the experiment PHELEX (PHoton-ELectron EXperiment) on the search for dark photons of cold dark matter using a technique of multi-cathode counter developed by us for thi…
Present Status Of The Experiment On The Search For Dark Photons By Multi-Cathode Counter
A. Kopylov, I. Orekhov, V. Petukhov
In this paper we describe the apparatus used in this experiment and the procedure of data treatment. We give the latest experimental results and discuss the possibility to observe…
Results from a Hidden Photon Dark Matter Search Using a Multi-Cathode Counter
A. Kopylov, I. Orekhov, V. Petukhov
Here we present measurements of the rates of emission of single electrons from the cathode of a proportional counter filled with a mixture of Ar + CH4 (10%) at 1 bar. We interpret…
Search for Hidden Photon Dark Matter Using a Multi-Cathode Counter
A. Kopylov, I. Orekhov, V. Petukhov
A search for hidden-photon (HP) dark matter using a multi-cathode counter is reported. The technique based on counting of single electrons emitted from outer cathode of the proport…
The Measurement of a Temperature Dependence of the Count Rate of Single Electrons Emitted From Copper by Means of a Multicathode Counter
Anatoly Kopylov, Igor Orekhov, Valery Petukhov
It was found that at cryogenic temperatures the spontaneous emission of single electrons from cathode of PMT is increased by lowering the temperature of PMT. This effect has not fo…
New results of the search for hidden photons by means of a multicathode counter
Anatoly Kopylov, Igor Orekhov, Valery Petukhov
New upper limit on a mixing parameter for hidden photons with a mass from 5 eV till 10 keV has been obtained from the results of measurements during 78 days in two configurations R…
